Astronomers struggle to understand how planets form in binary star systems. Early models suggested that the gravitational tug-of-war between two stellar bodies would send young planets into eccentric ...

We examine characteristics of circumbinary orbits in the context of current planet formation scenarios. Analytical perturbation theory predicts the existence of nested circumbinary orbits that are ...

Some of the brightest and hottest stars in existence may be formed by the collision of two other stars, astronomers have found. The formation of these intensely bright stars, called blue supergiants, ...

The binary star system ν Octantis has long been considered hostile to planet formation. The discovery of a white dwarf in the system offers an alternative view. However, Cheng and colleagues observe ...

N-body simulations of primordial binaries and tidal capture in open clusters / Sverre J. Aarseth -- When and how can binary data test stellar models / Birgitta Nordstrom / Johannes Anderson -- ...

An international team of researchers led by PD Dr Florian Peißker has found the first binary star in the immediate vicinity of the supermassive black hole Sgr A* (Sagittarius A star) at the centre of ...

Astronomers have identified a rare type of binary star system containing a rapidly spinning millisecond pulsar and a helium star companion, formed via common envelope evolution. Although such systems ...

Astronomers have confirmed a giant planet orbiting a tightly bound pair of young stars, marking a first in direct exoplanet imaging. The planet, known as HD 143811 AB b, is the closest-in world ever ...
